In this paper, we introduce and study a new sort of fuzzy n-ary sub-hypergroups of an n-ary hypergroup, called (is an element of, is an element of Vq)-fuzzy n-ary sub-hypergroup. By using this new idea, we consider the (is an element of, is an element of Vq)-fuzzy n-ary sub-hypergroup of a n-ary hypergroup. This newly defined (is an element of, is an element of Vq)-fuzzy n-ary sub-hypergroup is a generalization of the usual fuzzy n-ary sub-hypergroup. Finally, we consider the concept of implication-based fuzzy n-ary sub-hypergroup in an n-ary hypergroup and discuss the relations between them, in particular, the implication operators in Lukasiewicz system of continuous-valued logic are discussed.
